Chemistry Concentration and Molarity Lab Essay

I solved for my unknown by plugging in y as my given transmission value, which was 85.0. y = -278x + 100.12.85 = -278x + 100.12-99.27 = -278xX = .357M (concentration)The relationship between the transmittance values and the concentration is an indirect relationship. Whenever the concentration increases, the transmittance decreases. It can also be reversed, so when the concentration decreases, the transmittance increases. For this graph, the outline should not touch the origin because it is a negative slope. In run for the concentration to be 0, the transmittance level must be at exactly 100%. This means that all the light particles are transmit directly with the object without any levels of concentration.Y = 1.4599x 0.0068.07 = 1.4559x 0.0068X = 0.05The second graph was between concentration and absorbance. This is a direct relationship because as the concentration increased, the absorbance also increased. For this graph, the line should touch the origin because it is a arrog ant slope going from dishonor values to higher values. Also it passes with the origin because direct variation relationships are in the form of y = mx, where y and m are constant variables. For the absorbance value to zero, the concentration must be also be zero.Should the line of Concentration versus Absorbance go done the origin? As stated above, the line should touch and go through the origin eventually because it is a positive slope going from lower values to higher values. It is a direct variation relationship.
